Calculating Speed and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a cyclist travels 40 km in 2 hours, what is their average speed?

Back

Average Speed = 40 km / 2 hours = 20 km/h.

Front

What is the formula to convert cm/s to m/s?

Back

To convert cm/s to m/s, divide the speed in cm/s by 100.

Front

A car travels 150 km in 3 hours. What is its average speed?

Back

Average Speed = 150 km / 3 hours = 50 km/h.

Front

What is the unit of speed in the SI system?

Back

The unit of speed in the SI system is meters per second (m/s).

Front

If a train travels at a velocity of 60 mph east for 2 hours, how far does it travel?

Back

Distance = Velocity x Time = 60 mph x 2 hours = 120 miles.
